The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

ABSTRACT

Multichannel absorption spectroscopy has been used to determine simultaneously the temperature and absolute species concentrations in the gas-phase flame above solid propellant samples burning at pressures from 0.1 to 2.0 MPa. The apparatus consists of a windowed chamber, broad-band arc lamp and two 0.32-m spectrometers with intensified photodiode array detectors. Pinhole apertures, 0.1 and 0.2 mm in diameter, were mounted near the propellant samples to define the spatial resolution. Typically, 30 spectra were recorded during a propellant burn. Details of the analysis that account for the significant wavelength nonlinearity which is present in the data are given.
Sample spectra and analysis fits are presented for OH and NO from both laboratory flames and propellant burning at elevated pressures. Plots of the measurements of both the temperature and absolute concentrations of OH and NO as functions of distance from the surface of a sample propellant are presented. Measured mole fractions are as high as 0.20 for NO in the dark zone and 0.002 for OH in the post-luminous flame zone. Estimated total error in concentration measurements is 30%. Temperature errors are indicated to be 50 K from data fits and 100 K based on comparison of OH concentrations observed vs. those calculated thermochemically.
